HOT-All? REGISTER.

Specification of Letters Patent.

Patented March 13, 1906.

Application filed ii- 6 3D, 1995. Serial No- 252,315.

To all whom it may concern:

Be it known that 1, Hammer SYMONDS, a citizen of the United States, and a resident of East St. Louis, in the county of St. Clair, in i the State of Illinois, have invented certain new and useful Improvements in Hot-Air Registers, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in hot-air registers, and has for its obiect to provide a hot-air re ister of the wall type provided with a sing e valve and having the advantages as to economy of construction and efficiency of function hereinafter set forth.

In the drawings, Figure 1 is a perspective view of the register of my invention. Fig. 2 is a transverse vertical view of the same in mid-section. Fig. 3 is an enlarged transverse vertical view in mid-section, showing the manner in which the valve is attached to and supported by the grille. Fig. 4 is an enlarged longitudinal mid-sectional view of one of the intersecting strips composing the grille. Fig. 5 is a lan view of the upper portion of the back 0 the valve, showing its mode of attachment to the grille.

In the form shown in the drawi s I have provided a frame 1 and a reticulate ille 2, which are integral with each other an which may be stam ed from a single sheet of metal or be formed by a single casting, as preferred. The grille is composed of the cross-pieces 3, which are corrugated for stiflenin purposes, as indicated by the numeral 4, while at their points of intersection the said cross-pieces 3 present fiat lane surfaces, as ind cated by the numera 5. The sheet of metal is stamped, as shown in the drawings, the frame 1 bein provided with ornamental corrugations to insure its rigidity, and the rille 2 is depressed beneath or beyond the p ane of the outer surface of the frame 1, so that the plane of the surface of the grille when in position is parallel to the plane of the surface of the we and the inner face of the frame 1 is in contact with the face of the wall and directly attached thereto. The frame is provided with openings 6, through which screws or other fastening means may be inserted to screw the frame in its desired position upon the wall of the room to be heated.

By the construction of my grille and frame from a single sheet of metal I have entirely dispensed with the register-frames heretofore employed in this art and have supplied a sinle integral and ornamental device performlng all the functions of the face-plates and borders and re ister-frarnes of the prior art, and my device is attached directly to the face of the wall, savin not only the entire cost of the material and%abor entering into the old register-frames, but also the very considerallre cost of installing the register-frames in p ace.

A single valve 7 is mounted behind the grille 2 in the following manner by the following means: The valve 7 is preferabl composed of a sheet of resilient material 0 a sufficient size to completely cover the grille, the upper ed e of which sheet is bent over upon itself to arm the approximately cylindrical roll 8. This cylindrical transverse roll is preferably made in the form shown in section in Fig. 2, so that the edge of the roll does not contact with the back of the grille 7, whereby the roll 8 is given a considerable resiliency. The grille is provided at or near its top with one or more slots 9. Seated through the slots 9 are one or more hook-shaped memhere 10, which are provided at their outer ends with cars 11, which prevent their slipping through the slots 9. The hook-shaped members 10 being placed in position throu h the slots 9, the transverse cylindrical rol 8 of the grille is com ressed and sli ped into position within the liooks 10, so that it is embraced by said hooks 10 and held in position in the manner shown in section in Fig. 3. The inner sides of the hooks 1O combine with the roll 8 to form a hinge, and the resilient character of the roll 8 enables it to be held in close frictional contact with the inner surfaces of the hooks 10, so that by reason of the said friction the valve 7 will remain in any position with reference to the grille 2 m' which it may be placed. It is obvious that any number of the hooks 1 0 may be one loyed, their number dc ending upon the wi th and weight of the vs vs 7.

In order to provide the valve 7 with means whereby it may be opened and closed, I have provided a tongue 12, which is enlar ed at its outer end, as indicated at 13, and w ch is seated loosely throu h the opening 14 in the grille 2, its inner end mounted diametrically throu h the roll 8, as shown in section in Fig. 2. T e valve is opened or closediby the pressure of the foot or hand exerted upon the outer end of the tongue 12, and the frictional contact of the inner faces of the hooks 10 on the roll 8 serves, as above described, to hold the valve 7 in any desired osition, either partly opened or partly closed In the registers of the prior art in which a single valve has been employed the pivotal connection between the valve and the grille has been of such a character as to permit the loss of heat. In the register of my invention the upper edge of the valve 7 is held in close frictional contact throughout its entire width to the back of the grille 2, as shown in Fig. 2, thus preventing the waste of heat and making a perfectly close and practically air-tight hinge.

It is obvious that the tongue 12 must be of a length suflicient to secure the proper leverage upon the roll 8 to operate the valve 7, and t llS length must be so considerable in practice that it is both expedient and necessary to recess the grille2 in the manner shown in the drawings, so that the tongue 12 will not project much beyond the surface of the wall, as when so projected and at the height at which wall-registers are used it would be calculated to injure furniture or clothing accidentally brought in contact with it.

Having thus described my invention, what I claim as new, and desire to have secured to me by the grant of Letters Patent, is-

1. In a wall-register, the combination of an integral grille and frame, a valve mounted thereon, said valve having one of its edges formed into a roll and a member secured to said frame and curved to frictionally embrace said roll and thereby hinge said valve to said frame, so that the valve may be turned into and retained in any one of several posi tions of adjustment, substantially as specified.

2. In a wall-register, the combination of an integral grille and frame,a valve mounted thereon, said valve having one of its edges formed into a roll, a member secured to said frame and curved to frictionally embrace said roll and thereby hinge said valve to said frame, so that the valve may be turned into and retained in any one of several positions of adjustment, and means for openin and closin the valve, substantially as specified.

3. n a wall-register, the combination of an integral ille and frame,a valve mounted thereon, said valve having one of its edges formed into a roll, a member secured to said frame and curved to frictionally embrace said roll and thereby hinge said valve to said frame, so that the valve may be turned into and retained in any one of several ositions of ad ustment, and a tongue mounte through the roll and projecting through the grille to open and close the same, substantially as specified.

4. In a wall-register, acombinedgrilleand register-frame formed from a single metallic sheet, the frame being adapted to be directly attached to the face of the wall, and the grille being recessed from the plane of the outer surface of the frame, a valve pivotally mounted upon the inner face of the grille, and means for opening and closing the valve, substantially as specified.

In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses.

HERBERT SYMONDS.
